Here's a close-up. It's a pity I can't include photographs of my students on here (totally illegal) because I have a great shot of a group of sixth graders who built a triple-pulley. They were so proud of themselves! There wasn't anywhere high enough to hang the whole thing, though, so they had to hold the board up by hand. They went on to build a four-pulley system. Keep in mind this is the second-to-last day of school...
